Onychogomphus forcipatus, the Small Pincertail or 'Green-eyed Hook-tailed Dragonfly', is a species of 'dragonflies' belonging to the family Gomphidae.
This quite common and widespread 'dragonfly' is present in most of Europe. The adults grow up to 60 millimetres (2.4 in) long and can be encountered close to running water and lakes from June through September. Their life cycle lasts about 3-5 years.
The eyes of Onychogomphus forcipatus are widely separated and grey-to-green. The two black lines on the side of the thorax are relatively narrow and touch the midline. It has a yellow line on the 'vertex' and two cells above the anal triangle. The abdomed in males is fitted with three hooks of large size (anal appendages). 'Cercoids' may be dark and have a subterminal tooth. The base of the hindwing is angled in males and rounded in females.

Nice sharp capture from a typical POV. Nice colours on the abdomen and the eyes. The wings though merge in the very near grass in the BG and difficult to make out the typical hook on the tail from this POV.

Hello Luciano,
As usual a remarkable photo with exceptional clarity and details. This is a nice species of insectt with wonderful colors and very different from those I see here in my region. Nice composition taken from a excellent POV with lovely light and best clarity.
